later monuments of the Caesars. The traveller is always disappointed in contemplating the ruins of Greek buildings so far as size is concerned. But it is their matchless proportions, their severe symmetry, the grandeur of effect, the undying beauty, the graceful form which impress us, and make us feel that they are perfect. By the side of the Colosseum they are insignificant in magnitude; they do not cover acres, like the baths of Caracalla. Yet who has copied the Flavian amphitheatre; who erects an edifice after the style of the Thermae? All artists, however, copy the Parthenon. That, and not the colossal monuments of the Caesars, reappears in the capitals of Europe, and stimulates the genius of a Michael Angelo or a Christopher Wren.
The flourishing period of Greek architecture was during the period from Pericles to Alexander,–one hundred and thirteen years. The Macedonian conquest introduced more magnificence and less simplicity. The Roman conquest accelerated the decline in severe taste, when different orders began to be used indiscriminately.
In this state the art passed into the hands of the masters of the world, and they inaugurated a new era in architecture. The art was still essentially Greek, although the Romans derived their first knowledge from the Etruscans. The Cloaca Maxima, or Great Sewer, was built during the reign of the second Tarquin,–the grandest monument of the reign of the kings. It is not probable that temples and other public buildings in Rome were either beautiful or magnificent until the conquest of Greece, after which Grecian architects were employed. The Romans adopted the Corinthian style, which they made even more ornamental; and by the successful combination of the Etruscan arch with the Grecian column they laid the foundation of a new and original style, susceptible of great variety and magnificence. They entered into architecture with the enthusiasm of their teachers, but in their passion for novelty lost sight of the simplicity which is the great fascination of a Doric temple. Says Memes:–
"They [the Romans] deemed that lightness and grace were to be attained not so much by proportion between the vertical and the horizontal as by the comparative slenderness of the former. Hence we see a poverty in Roman architecture in the midst of profuse ornament. The great error was a constant aim to lessen the diameter while they increased the elevation of the columns. Hence the massive simplicity and severe grandeur of the ancient Doric disappear in the Roman, the characteristics of the order being frittered down into a multiplicity of minute details."
When the Romans used the Doric at all, they used a base for the column, which was never done at Athens. They also altered the Doric capital, which cannot be improved. Again, most of the Grecian Doric temples were peripteral,–surrounded with pillars on all the sides. But the Romans built with porticos on one front only, which had a greater projection than the Grecian. They generally were projected three columns, while the Greek portico had usually but a single row. Many of the Roman temples are circular, like the Pantheon, which has a portico of eight columns projected to the depth of three. Nor did the Romans construct hypaethral or uncovered temples with internal columns, like the Greeks. The Pantheon is an exception, since the dome has an open eye; and one great ornament of this beautiful structure is in the arrangement of internal columns placed in the front of niches, composed of antae, or pier-formed ends of walls, to carry an entablature round under an attic on which the cupola rests. The Romans also adopted coupled columns, broken and recessed entablatures, and pedestals, which are considered blemishes. They again paid more attention to the interior than to the exterior decoration of their palaces and baths,–as we may infer from the ruins of Hadrian's villa at Tivoli and the excavations of Pompeii.
The pediments (roof-angles) used in Roman architectural works are steeper than those made by the Greeks, varying in inclination from eighteen to twenty-five degrees, instead of fourteen. The mouldings are the same as the Grecian in general form, although they differ from them in contour; they are less delicate and graceful, but were used in great profusion. Roman architecture is overdone with ornament, every moulding carved, and every straight surface sculptured with foliage or historical subjects in relief. The ornaments of the frieze consist of foliage and animals, with a variety of other things. The great exuberance of ornament is considered a defect, although when applied to some structures it is exceedingly beautiful. In the time of the first Caesars Roman architecture had, from the huge size of the buildings, a character of grandeur and magnificence. Columns and arches appeared in all the leading public buildings,–columns generally forming the external and arches the internal construction. Fabric after fabric arose on the ruins of others. The Flavii supplanted the edifices of Nero, which ministered to debauchery, by structures of public utility.
The Romans invented no new principle in architecture, unless it be the arch, which was known, though not practically applied, by the Assyrians, Egyptians, and Greeks. The Romans were a practical and utilitarian people, and needed for their various structures greater economy of material than was compatible with large blocks of stone, especially for such as were carried to great altitudes. The arch supplied this want, and is perhaps the greatest invention ever made in architecture. No instance of its adoption occurs in the construction of Greek edifices before Greece became a part of the Roman empire. Its application dates back to the Cloaca Maxima, and may have been of Etrurian invention. Some maintain that Archimedes of Sicily was the inventor of the arch; but to whomsoever the glory of the invention is due, it is certain that the Romans were the first of European nations to make a practical application of its wonderful qualities. It enabled them to rear vast edifices with the humblest materials, to build bridges, aqueducts, sewers, amphitheatres, and triumphal arches, as well as temples and palaces. The merits of the arch have never been lost sight of by succeeding generations, and it is an essential element in the magnificent Gothic cathedrals of the Middle Ages. Its application extends to domes and cupolas, to floors and corridors and roofs, and to various other parts of buildings where economy of material and labor is desired. It was applied extensively to doorways and windows, and is an ornament as well as a utility. The most imposing forms of Roman architecture may be traced to a knowledge of the properties of the arch, and as brick was more extensively used than any other material, the arch was invaluable. The imperial palace on Mount Palatine, the Pantheon (except its portico and internal columns), the temples of Peace, of Venus and Rome, and of Minerva Medica, were of brick. So were the great baths of Titus, Caracalla, and Diocletian, the villa of Hadrian, the city walls, the villa of Mecaenas at Tivoli, and most of the palaces of the nobility,–although, like many of the temples, they were faced with stone. The Colosseum was of travertine, a cheap white limestone, and faced with marble. It was another custom to stucco the surface of brick walls, as favorable to decorations. In consequence of the invention of the arch, the Romans erected a greater variety of fine structures than either the Greeks or Egyptians, whose public edifices were chiefly confined to temples. The arch entered into almost every structure, public or private, and superseded the use of long stone-beams, which were necessary in the Grecian temples, as also of wooden timbers, in the use of which the Romans were not skilled, and which do not really pertain to architecture: an imposing edifice must always be constructed of stone or brick. The arch also enabled the Romans to economize in the use of costly marbles, of which they were very fond, as well as of other stones. Some of the finest columns were made of Egyptian granite, very highly polished.
The extensive application of the arch doubtless led to the deterioration of the Grecian architecture, since it blended columns with arcades, and thus impaired the harmony which so peculiarly marked the temples of Athens and Corinth; and as taste became vitiated with the decline of the empire, monstrous combinations took place, which were a great fall from the simplicity of the Parthenon and the interior of the Pantheon.
But whatever defects marked the age of Diocletian and Constantine, it can never be questioned that the Romans carried architecture to a perfection rarely attained in our times. They may not have equalled the severe simplicity of their teachers the Greeks, but they surpassed them in the richness of their decorations, and in all buildings designed for utility, especially in private houses and baths and theatres.
The Romans do not seem to have used other than semicircular arches. The Gothic, or Pointed, or Christian architecture, as it has been variously called, was the creation of the Middle Ages, and arose almost simultaneously in Europe after the first Crusade, so that it would seem to be of Eastern origin. But it was a graft on the old Roman arch, in the curve of the ellipse rather than the circle.
